Key result
Single coronary artery anomaly presents as myocardial infarction in a rare case report.
Why the study?
The presence of a single coronary artery is a rare congenital anomaly with few reported cases associated with myocardial infarction or ischemia.
Case Report (n=1)
Alerts clinicians to MI risk with single coronary artery; leaves open optimal management in this rare anomaly.
THE PRESENCE of a single coronary artery falls into the spectrum of congenital anomalies of the coronary arteries1which have been recognized with increasing frequency in the past several years. However, this condition is sufficiently rare that only 74 cases have been reported in the literature. The study of Alexander and Griffith2showed that some form of anomaly was present in the coronary arteries in 2.85 per 1,000 autopsies. In this series of 18,950 autopsies, only seven had a single coronary artery which gave an incidence of 0.36 per 1,000 autopsies. Of the 74 reported cases, 47 were in adults. Only eight of the adult cases have been associated with myocardial infarction or myocardial ischemia. For this reason, the present case is being reported.

George L. Allen (1966) conducted a case report in Myocardial infarction with a single coronary artery (n=1). Single coronary artery was evaluated. A 54-year-old man experienced a myocardial infarction associated with a single coronary artery, a rare congenital anomaly with an estimated autopsy incidence of 0.36 per 1,000.
